Why are 99.9% of physical doors opened by keys and not by passwords?
Because humans prefer to look for the key in their pocket instead of searching for the password in their memory. Humans don't like passwords!
- they don't like to type them, and they even less like to memorize them.

For the virtual doors within the Internet there were no such keys available until recently - so there was no other way but passwords. But nowadays the smartphones are able to play this ''key'' role: they are able to become the key ring of the user for his online portals.

For most of the online portals a 2-factor authentication is not necessary - usually a replacement of the password by the smartphone is enough. There are no 2-factor physical doors - why should virtual doors be 2-factor?

After 70 years of computers, 45 years of Internet, and 20 years of WWW: Leave the password stone-age - and turn your smartphone into the key for your online portals!

More information:

The eKaay log-in is a 1-factor something-you-have authentication, like a key.

In case the user or the portal wants to have very high security, eKaay can be made a 2-factor authentication method. There are serveral ways, for example via an additional password on the PC, or a PIN protection on the smartphone (''App-PIN'').
But the best way is eKaay PIN because that PIN is not tappable -
neither on the PC nor on the smartphone.

There is no central eKaay ID-server. In other words, once installed at a portal eKaay is just a bilateral system among the portal server and its users, like the password method.

For portals which have their own app eKaay can be integrated easily into the app via a QR code scanner library (Android and iPhone).

eKaay can easily be integrated into single-sign-on clusters of portals.
